An artificial satellite placed into earth's orbit has a mass of 1250kg. It travels at an average distance of 222.5km above the surface of the earth. The radius of the earth is 6370km. What acceleration due to gravity does the earth give the satellite?
I know to find the distance you add both the kms together.
a=g
a=6.593x10^6 m?
thanks in advance

acceleration=GMe/(re+alt)^2

acceleration=[(6.67x10^11)(1250kg)]/(6.593x10^6)^2=1.92x10^21
Are the numbers plugged in correctly? The answer seems off.
